Because sewer pipes generally have traps, it is more complicated to dredge sewer pipes, and the pipes are smaller and deeper. If it's a kitchen pipe, it's still greasy. It is difficult to dredge with ordinary objects, and only dredge can be used.
If professional dredge personnel are invited to dredge sewers, it will probably take about 80 yuan.
If you buy your own dredging machine, you only need about 120 yuan, and you can dredge all the sewers in your home, and you can also dredge the blocked toilets for future trouble. (In addition, electric drills can also be used for other purposes.)
I just sold one myself, which is very convenient and good when dredging.
